Effect of microwave disinfection on physical and mechanical properties of acrylic resins
(2008-12-01)
This study evaluated the effect of microwave energy on the hardness, impact strength and flexural strength of the Clássico, Onda-Cryl and QC-20 acrylic resins. Aluminum die were embedded in metallic or plastic flasks with ...
Influence of microwave energy on structural and piezoelectric response of Bi 4Ti 3O 12 ceramics
(2010-12-01)
Bismuth titanate ceramics (Bi 4Ti 3O 12) with 10 wt% in excess of bismuth (BIT10) were prepared by the polymeric precursor method and sinterized in microwave (MW) and conventional furnaces (CF). The effect of microwave ...
Asymmetrical penetration of microwave in a conducting media and determination of microwave conductivity for very thin samples using electron spin resonance
(Elsevier B.V., 2001-05-01)
Dyson's theory of conduction electron spin resonance (CESR) has been used in the limit d less than or equal to delta (d being the thickness of the sample and delta the skin depth of the microwave field) to obtain the ...
Changes in occlusal vertical dimension in microwave processing of complete dentures.
(2002-11-13)
This study investigated the effect of different microwave curing cycles on the changes in occlusal vertical dimension of complete dentures. Four test groups with 12 maxillary dentures each were evaluated. Groups 1, 2 and ...
The occurrence of porosity in reline acrylic resins. Effect of microwave disinfection
(Wiley-Blackwell Publishing, Inc, 2009-03-01)
Microwave energy has proved to be an effective method for disinfecting acrylic dentures. However, the effect of microwave heating on the porosity of autopolymerising denture reline resins has not been investigated.The ...
Microwave Disinfection of Complete Dentures Contaminated In Vitro with Selected Bacteria
(Wiley-Blackwell, 2009-10-01)
Purpose: This study evaluated the effectiveness of microwave irradiation for disinfection of simulated complete dentures.Materials and Methods: Seventy dentures were fabricated in a standardized procedure, subjected to ...
Denture disinfection by microwave irradiation: A randomized clinical study
(Elsevier B.V., 2009-09-01)
Objective: This study evaluated the clinical effectiveness of two exposure times of microwave irradiation on the disinfection of complete dentures.Methods: Biofilm samples were collected from dentures of 30 patients, who ...
Synthesis of wurtzite ZnS nanoparticles using the microwave assisted solvothermal method
(2013-04-15)
In this article, we report the development of an efficient and rapid microwave assisted solvothermal (MAS) method to prepare wurtzite ZnS nanoparticles at 413 K using different precursors. The materials obtained were ...
Synthesis and characterization of CaBi4Ti4O15 thin films annealed by microwave and conventional furnaces
(Elsevier B.V., 2007-08-01)
CaBi4Ti4O15 thin films were deposited by the polymeric precursor method and crystallized in a domestic microwave oven and conventional furnace. The films obtained for microwave energy are well-adhered, homogeneous and with ...
